Abstract:
A chip-like electric component such as a chip resistor is provided, which is easy to manufacture and in which cracks or fractures of an insulating substrate are unlikely to occur. A pair of surface electrodes 21, 23 are formed so that thicknesses of the pair of surface electrodes increase from a resistor layer 13 toward end portions 30 of an insulating substrate 29 in a direction in which the pair of surface electrodes 21, 23 are arranged. A plating reservoir S is formed between one of the surface electrodes 21, 23 and an insulating protective layer 15. When forming at least one plated layer 33, a plated metal pools in the plating reservoir S. The at least one plated layer 33 may work to reduce to some extent a height difference between a soldering electrode portion 21, 23, 27, 33 and the insulating protective layer 15.
